Manganflurlite is a rare phosphate mineral typically found in complex granite pegmatites as a product of secondary alteration. It is best identified by its distinct yellowish-brown hues and its occurrence within phosphate-rich zones alongside other rare minerals like triphylite.
Is this manganflurlite?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch manganflurlite with a known reference. Manganflurlite sits at Mohs 4-4.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Manganflurlite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Manganflurlite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: yellow, brownish-yellow, orange-brown.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: tabular crystals, massive.

Field-hunting tip
Look in granite pegmatites country — that is the host setting where manganflurlite typically forms. If you start seeing triphylite, phosphophyllite, strengite in float, you are in the right ground. Field specimens usually show a tabular crystals, massive habit, so train your eye for that shape before scanning the outcrop.
